Variables | |
msg_hclass_t | sip_content_type_class [] |
Header class for Content-Type header. | |
tag_typedef_t | siptag_content_type |
Tag for Content-Type header object. | |
tag_typedef_t | siptag_content_type_str |
Tag for string with Content-Type header value. | |
#define SIP_CONTENT_TYPE_INIT | ( | ) |
Initializer for structure sip_content_type_t.
A static sip_content_type_t structure for Content-Type header must be initialized with the SIP_CONTENT_TYPE_INIT() macro. For instance,
#define SIPTAG_CONTENT_TYPE | ( | x | ) |
Tag list item for pointer to a Content-Type header structure sip_content_type_t.
The SIPTAG_CONTENT_TYPE() macro is used to include a tag item with a pointer to a sip_content_type_t structure in a tag list.
x | pointer to a sip_content_type_t structure, or NULL. |
The corresponding tag taking reference parameter is SIPTAG_CONTENT_TYPE_REF().
#define SIPTAG_CONTENT_TYPE_STR | ( | s | ) |
Tag list item for string with Content-Type header value.
The SIPTAG_CONTENT_TYPE_STR() macro is used to include a tag item with a string containing value of a sip_content_type_t header in a tag list.
s | pointer to a string containing Content-Type header value, or NULL. |
The string in SIPTAG_CONTENT_TYPE_STR() can be converted to a sip_content_type_t header structure by giving the string s has second argument to function sip_content_type_make().
The corresponding tag taking reference parameter is SIPTAG_CONTENT_TYPE_STR_REF().

Copy a list of Content-Type header header structures sip_content_type_t.
The function sip_content_type_copy() copies a header structure hdr. If the header structure hdr contains a reference (hdr->h_next
) to a list of headers, all the headers in that list are copied, too. The function uses given memory home to allocate all the memory areas used to copy the list of header structure hdr.
home | memory home used to allocate new structure |
hdr | pointer to the header structure to be copied |
When copying, only the header structure and parameter lists attached to it are duplicated. The new header structure retains all the references to the strings within the old hdr header, including the encoding of the old header, if present.

inline |
Duplicate a list of Content-Type header header structures sip_content_type_t.
Duplicate a header structure hdr. If the header structure hdr contains a reference (hdr->x_next
) to a list of headers, all the headers in the list are duplicated, too.
home | memory home used to allocate new structure |
hdr | header structure to be duplicated |
When duplicating, all parameter lists and non-constant strings attached to the header are copied, too. The function uses given memory home to allocate all the memory areas used to copy the header.
|
inline |
Make a Content-Type header from formatting result.
Make a new sip_content_type_t object using formatting result as its value. The function first prints the arguments according to the format fmt specified. Then it allocates a new header structure, and parses the formatting result to the structure sip_content_type_t.
home | memory home used to allocate new header structure. |
fmt | string used as a printf()-style format |
... | argument list for format |
|
inline |
Initialize a structure sip_content_type_t.
An sip_content_type_t structure for Content-Type header can be initialized with the sip_content_type_init() function/macro. For instance,
|
inline |
Make a Content-Type header structure sip_content_type_t.
The function sip_content_type_make() makes a new sip_content_type_t header structure. It allocates a new header structure, and decodes the string s as the value of the structure.
home | memory home used to allocate new header structure. |
s | string to be decoded as value of the new header structure |
|
inline |
Test if header object is instance of sip_content_type_t.
Check if the header class is an instance of Content-Type header object and return true (nonzero), otherwise return false (zero).
header | pointer to the header structure to be tested |
1 | (true) if the header is an instance of header content_type |
0 | (false) otherwise |

Header class for Content-Type header.
The header class sip_content_type_class defines how a SIP Content-Type header is parsed and printed. It also contains methods used by SIP parser and other functions to manipulate the sip_content_type_t header structure.
